We propose a novel plant-based amphiphilic diblock co-oligomers (BCO) surfactant containing only carbohydrate segments and examine its potential as a biosourced stabilizer. The synthesis of an amphiphilic xyloglucan-based BCO, composed of a hydrophilic xyloglucan oligosaccharide (XGO) block clicked to a hydrophobic peracetylated XGO is described. Dynamic light scattering experiments correlated with transmission electron microscopy observations showed that this new class of amphiphilic BCO self-assembles in water to form spherical micelles with a hydrodynamic diameter of 22 nm. Preliminary studies indicate that the XGO-based BCO sterically stabilizes gliadin and zein nanoparticle suspensions. The stabilization results were compared to those using pluronic F-68, a commercial surfactant. For gliadin nanoparticles, both surfactants result in essentially the same morphology and polydispersity. However, for the zein nanoparticles, the XGO-based BCO stabilizer gave lower polydispersity.
